ROTOCON Rotary Ground rated to 10,000+ Amps continuous

ROTOCON® ERG-10000 Model Specifications

»  Provides consistent low and stable resistance for high current applications»  Robust industrial design provides reliable long lasting performance
»  Requires ZERO grease or routine maintenance»  Remains unaffected by RPM or total number of revolutions

Designed for currents up to 10,000A+, the ERG-10000 provides a low-resistance and stable grounding path for current to flow  The entire high-current ERG Series by Meridian Laboratory provides the perfect ground for rotational welding, plating, polishing, and other high-current applications that require rotation. It is designed to withstand 100% duty cycles in continuous manufacturing and production processes, without interruption or downtime.

Conventional brushed rotary grounds rely on a metal-on-metal contact and are prone to arcing, wear, and high fluctuations in current due to changes in resistance, Meridian Laboratory’s ERG Series are arc-free, provide low and stable resistance, and do not require greasing or any type of maintenance.
